|x-7|=7

Lösung

∣ x - 7 ∣ = 7

x = 0 or x = 14

Schritte zur Lösung

∣ x - 7 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 7 = - 7 or x - 7 = 7

x - 7 = - 7 or x - 7 = 7

x = 0 or x = 14

\frac{a}{5} < 1

\frac{3}{4} x + \frac{5}{4} = - \frac{7}{4}

f a c t or 8 ab - 56 a

a^{2} - 4 a = 0

x^{2} - (\frac{x}{2})^{2} = 3
